Title: Engine starting device
Inventor: OSADA MASAHIKO
IPC: F02N11/08
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To shorten the period of time for starting an engine without complicating the system. SOLUTION: When the engine enters the economical running auto-stop mode, a control circuit 10 turns a control element 9 on receiving a control signal outputted from an ECU 2, and gradually increases the electric current running in a coil 3 by the PWM control of the control element 9. After that, a plunger 4 is stopped on the way of moving so that a pinion gear 6 pushed out by interlocking with the movement of the plunger 4 can be held at the position where the pinion gear 6 abuts to a ring gear. In this case, the plunger 4 is stopped by inhibiting the current running in the coil 3 and restricting the suction force against the plunger 4. Then, when the engine enters the economical running auto-start mode, the plunger 4 is moved by increasing the electric current running in the coil 3, closing a connecting point 7, and the electric current is sent to an armature 8.  Accordingly, the rotation of the armature 8 is transmitted from the pinion gear 6 to the ring gear, and the engine is started.

Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a starter control method, providing compatibility between durability of a starter and quickness of an engine start, even when idle-stop is carried out. SOLUTION: This starter control method is a method for controlling a pinion, a motor, and an engine starter having a magnet switch having a coil and a plunger, causing the pinion to protrude toward a ring gear.

Filed: 2001-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the Coulomb effect of a charged particle beam exposure system can be corrected accurately by accurately grasping the gradation of the Coulomb effect by accurately and simply calculating stochastic blur. SOLUTION: The unmarked solid line in Fig. (a) indicates the stochastic blur.
